Head-to-head

Frigidaire FHWW125WE1 vs LG LW1022IVSM: Frigidaire adds capacity, LG fits a narrower or lower opening

The short answer

Choose Frigidaire for an adjusted cooling load near 12,000 BTU and a room around 550 square feet. Choose LG when 10,000 BTU is enough and the window opening is too narrow or low for the larger Frigidaire.

About this comparison

Frigidaire FHWW125WE1 and LG LW1022IVSM compared by cooling capacity, window fit, compressor and controls.

The practical choice turns on cooling capacity and window fit, then on the constraints in your own setup.

Before you choose

How they fit your plans

A sunny shared office can justify the Frigidaire step up

For an illustrative 450-square-foot office with strong sun and three regular occupants, the simple sizing guide reaches 11,600 BTU. That puts Frigidaire’s 12,000 rating closer than LG’s 10,000. A shaded room with fewer occupants can lead to a different choice. Use the example to check your own assumptions rather than applying it to every 450-square-foot room.

Facts behind this advice

ENERGY STAR starts at 10,000 BTU for 400 to 450 sq ft with an 8 ft ceiling. 10,000 × 1.10 + 600 = 11,600 BTU. This is an initial sizing screen.

The higher-output model can fail the window check

Frigidaire needs a window at least 25 inches wide and 15.5 inches high. LG’s documented minimums are 22 and 13 inches. A narrow opening can therefore make LG installable even though Frigidaire has the better capacity for the room. If LG is undersized for the heat load, find another installation solution rather than forcing a larger unit into the frame.

Facts behind this advice

Frigidaire minimum opening: 25 W by 15.5 H inches. LG minimum opening: 22 W by 13 H inches. Both maximum widths are 36 inches.
